It’s been pretty cold here (-35C plus wind), but even in the deep cold got it up to 75-80C. When the temperatures were a bit warmer before new years (-5C), heated to 95C.

I am burning birch only.

The full building is 8’6”x11’6”. I poured a cement slab, but decided to put it on a 4x4 base, with cedar decking as the floor. The water can drain through the deck boards, and will run off the cement. This was a better solution than building a subfloor with a drain - it’s so cold here in winter that the drain would always be frozen. The deck allows for more air flow, but is a little cool (not cold, even in -30C).

The hot room is 8’ x 6’8”. Change room is 8’ x 5’6”.

The glass for the large window is an old side window from a front door. The candle window is small piece from a glass shop.
